What is the best refresh rate for tv?

Answer 1

Frame rates vary depending on the video standard used. In North America and other areas that use NTSC as the standard definition color system, the standard frame rate is 29.97Hz. When the signal is interlaced (Standard definition, and 1080i in high definition) two fields are used to make a complete frame, so the field rate is 59.94Hz. High definition 720p is non interlaced, so the frame rate is 59.94Hz. In Europe, PAL is the color system and the frame rate is 25Hz, with a 50Hz field rate.

Answer 2

The true refresh rate of a television is defined by the incoming signal rather than the television itself. In North America, the rate is 59.94Hz and Europe is 50Hz. These are the standard broadcast field rates although some others can be found. Occasionally, film based content may be run at 24Hz which will follow the frame rate of the film used to capture the content.

Some of the larger and higher priced televisions offer higher frame rates such as 100Hz or 120Hz. Whatever the final refresh rates, more fields are drawn to the screen than are received by the television. The intermediate fields are calculated and built from the incoming frames, a technique known as interpolation. The aim is to deliver less flicker and smoother fast movement on the screen. Some televisions achieve these aims well while others are not as successful.

Before investing the additional money for a high refresh rate television, it is important to audition the television. If you cannot notice the difference between standard frame rates and the higher rate generated by the television, the extra cost simply isn't worthwhile. To make the best judgement, make sure that you are watching the type of program that you will watch at home. Images of wide, flowing landscapes aren't representative of the final quality when watching sport for example.

Remember always that the best television is the one that you enjoy watching, and that may not be the one with the best written specification.
